To increase the regulatory acceptance of (Q)SAR methods, the OECD is developing a QSAR Toolbox to make (Q)SAR technology readily accessible, transparent, and less demanding in terms of infrastructure costs.
5 February 2018 -OECD launches the QSAR Toolbox version 4.2.
For the complete list of new features please see the release notes.
21 September 2017 - A patch for QSAR Toolbox version 4.1 was released to address an installation issue and a few additional bugs.
The Toolbox is a software application intended to the use of governments, chemical industry and other stakeholders in filling gaps in (eco)toxicity data needed for assessing the hazards of chemicals. The Toolbox incorporates information and tools from various sources into a logical workflow. Crucial to this workflow is grouping chemicals into chemical categories. Download our brochure (PDF).
The seminal features of the Toolbox are:
The toolbox also provides an approach to predict skin sensitisation based on the concept of Adverse Outcome Pathways. The Toolbox has been developed in several phases:
The purpose of this webinar was to demonstrate the new features of Version 4.0 of the QSAR Toolbox.
OECD: Brief overview of the purpose & history of the QSAR Toolbox. Basic concepts and organisation of the Toolbox including workflow, profilers, databases. Where to get support for Version 4.0 (tutorials, discussion forum).
ECHA: Practical examples for the use of the QSAR Toolbox v4.0, with focus on the new functionalities. Relevance of profilers and databases for a given endpoint. Automated and standardised workflows. Quantitative metabolic information. Improved reporting: new prediction report and exportable data matrix in excel format.
The functionalities of the new version were presented at the 2017 IT tools training during ECHA´s stakeholders´ day.
